Capitalists just take.
They serve nobody else but themselves.
Preaching doesn't make it so.
In reality, without capitalists we would be far behind where we are now. They're what drives most large endeavors.
Calling things you don't like "preaching" has very little interest to me.
Mislabeling things is how capitalists operate.
We have a worsening but somewhat decent existence thanks to unions and workers. Thanks to anti-capitalist activity.
But as the unions have been crushed the lifestyle of millions is worsening.
1) Lifestyle isn't worsening.
2) You're focusing on the short term, anyway--seed corn is tasty.
Hard to say what alternatives might have done.
The US violently prevented any alternative. US capitalists have attacked and weakened the unions and the government has not cared.
Ever heard of the Vietnam War?
We tried to prevent a communist-backed dictatorship from taking over.
The crushing of democracy in Iran?
Democracy? Or another attempt to install a puppet
The support of violent dictators in Chile?
The proxy war in Nicaragua?
The refusal to trade with Cuba driving them to the Soviets?
In each case you are talking about groups that allied with our enemies. That's the important factor.
Look at the world--your beloved communism is dead because it never worked.
